Quota Minifilter Driver Metadata Integrity

Updated: January 27, 2011

Applies To: Windows Server 2008

To enforce quotas, the quota minifilter driver uses configuration information that is stored in a metadata file. If there is a problem with this metadata file, the quota minifilter driver cannot attach to the volume, and users might be able to exceed their quota limits.

Events

The quota minifilter driver failed to attach to volume "%2 (%5)" because the
minifilter metadata on the volume is the wrong version (version 0x%3 when
version 0x%4 was expected). This is most likely caused by a driver upgrade
followed by a restore of old metadata or by a metadata corruption. While
the driver is detached quota enforcement, and management will be unavailable
on the volume. Try to reinstall the driver or restore a newer version of
your quota configuration metadata.

The quota minifilter driver failed to attach to volume "%2 (%3)" because the
minifilter metadata on the volume is corrupt. While the minifilter is detached
quota enforcement, and management will be unavailable on the volume. Attempt
to restore the quota configuration metadata for this volume from backup.

The quota minifilter driver detected and deleted an invalid quota configuration
record on volume "%2 (%3)". The minifilter was unable to determine what directory
was affected. You can either restore the quota configuration for the volume
from backup or use the management tools to review the configuration and
reconfigure any missing entries.
